Hey Storm29,
I have the 80mm Stu Max in my Habu 32 and really love it... I have run the stock fan and it, both of 6s 5000mah. The Stu Max has a little more performance, mostly in the vertical, but the sound is great!!
You can contact Stu direct: http://www.stumaxaircraft.com/pages/contact.htm
or maybe find one at esprite: http://www.espritmodel.com/edf-stuma...het-motor.aspx

There is also the Jet Fan 80 which has a nice sound also: http://www.effluxrc.com/Jetfan-80mm-...t-JF-80EDF.htm

or the Wemo 80: http://www.extremerc.com.au/estore/i...oducts_id=1297

Hope that helps... all great fans, but I like Stu's the best
Ron
